Windows Vista DVD maker

I get a "unspecified error" message when trying to burn a DVD witch Windows
Vista DVD maker.

With Windows Vista Movie maker I created some wedding movies, pictures and
mp3 music together. When I press Publish movie, it opens DVD maker.
I chose the menu setup, and than I tried to burn it. But I get the following
error message:
"cannot create DVD. Unspecified error". DVD maker was busy with encoding and
every time at 1.8% I this error message.

I noticed the preview of the DVD menu did not went very well, but ignored it
further. Could there be the problem?

Can someone help me out?
